Crate feeless[−][src]

A set of tools to handle many aspects of the Nano cryptocurrency.

See the feeless.dev website for more details about this project.

Keys and signing example

use feeless::Phrase;
use feeless::phrase::Language;

// Example phrase from https://docs.nano.org/integration-guides/key-management/#test-vectors
let words = "edge defense waste choose enrich upon flee junk siren film clown finish
             luggage leader kid quick brick print evidence swap drill paddle truly occur";

// Generate the private key from the seed phrase.
let phrase = Phrase::from_words(Language::English, words)?;

// First account with the password `some password`.
let private_key = phrase.to_private(0, "some password")?;
let public_key = private_key.to_public()?;
let address = public_key.to_address();

// The above three lines can be chained like this:
let address = phrase.to_private(0, "some password")?.to_public()?.to_address();
assert_eq!(address.to_string(), "nano_1pu7p5n3ghq1i1p4rhmek41f5add1uh34xpb94nkbxe8g4a6x1p69emk8y1d");
     
// Sign a message.
let message = "secret message!".as_bytes();
let signature = private_key.sign(message)?;

// Someone else can verify the message based on your address or public key.
address.to_public().verify(message, &signature)?;
public_key.verify(message, &signature)?;

Modules

blocks	Handling, creating and parsing blocks.
phrase	BIP39 and BIP44 mnemonic seed phrase.
units	Units of Nano, i.e. Rai, Nano (10³⁰), Cents (10²²), MicroNano (10²⁴).
vanity
wallet	File storage for seeds and private keys.

Structs

Address	Nano address. e.g. `nano_3o3nkaqbgxbuhmcrf38tpxyhsf5semmcahejyk9z5ybffm7tjhizrfqo7xkg`
Phrase	BIP39 and BIP44 mnemonic seed phrase that can generate keys.
Private	256 bit private key which can generate a public key.
Public	256 bit public key which can be converted into an Address or verify a Signature.
Rai	Special bounded container for the smallest unit, rai.
Seed	256 bit seed used to derive multiple addresses.
Signature	A ed25519+blake2 signature that can be generated with Private and checked with Public.
Work	The result of some proof of work (PoW). Can verify and inefficiently generate PoW using the CPU.
